Hi,

I am using netcat and have 2 computers (XP).

On computer A I say netcat to listen on 1235 and execute cmd

(nc -v -L -p 1235 -e cmd.exe)

On computer B I try to connect to computer A with the command

(nc 192.168.1.2 1235) and it connects just fine. BUT if I put instead of 192.168.1.2 the external ip of computer A, it does not work (nc 94.67.xx.xx 1235)

Does someone know why??

if they are behind a router you would need to forward the port on the router to the correct internal address. But you really don't want to do that as any one would be able to connect to the listening port. It would be telnet but without the plain text authentication! You should use FreeSSHd instead.
